COMMISSIONING FIRE-LIFE SAFETY SYSTEMS 2008 ACG Annual Meeting Presenter: Mark Leafstedt, PE, CxA Best Practices for Total Building Commissioning! Agenda ¡ Viva Las Vegas ! Fire Life Safety Building Codes Means & Methods of Fire Life Safety Commissioning Conclusion Viva Las Vegas Statistics According to 2005 statistics published by Insider Viewpoint Las Vegas: 80+ major casinos 133,000 hotel rooms w/ 89.2% occupancy (20,000+ more open by 2010) 38.6 million tourists • >25 billion $ in current construction • 7 out of the top 10 world’s largest hotels reside within a five-mile radius of each other in Las Vegas • The largest hotel has approximately 5500 guest rooms Viva Las Vegas Relationship to Commissioning 100% growth each year since 1950 = More construction Schedule = Liquidated damages of up to $7 million a day Dependency on tourism = Occupant comfort is paramount Reputation = Need for safety and strictest codes in the country High occupancy = Little to no time for maintenance Viva Las Vegas Life Safety Cx vs Building Cx Building Commissioning is an owner-driven requirements. Smoke Control/ Life Safety Commissioning is a Code driven requirement. Viva Las Vegas The MGM Grand Fire WHAT? 1980 fire swept through the 26-story hotel, killing 84 and injuring 679. There were about 5,000 people in the hotel at the time. This was the second largest hotel fire in history. It started in the first floor restaurant and spread at a rate of 19 feet per second. A massive fireball traveled through the casino and blew through the glass entrance doors, injuring people and destroying cars. Viva Las Vegas The MGM Grand Fire WHY? A wire was not properly grounded. …all of which “could have been found had the area been inspected.” A compressor was not properly installed. A piece of copper was not insulated correctly. A supposedly smoke-free stairwell that was a crucial escape route filled with smoke. The laundry chutes failed to seal, and defects existed in the HVAC system -- all contributing to the spread of smoke.” A fire alarm never sounded. The Hotel had refused to pay for the $192,000 sprinkler system.

Just 3 months later, there was a fire in the Las Vegas Hilton that resulted in 8 dead and 198 injured. Viva Las Vegas Results of the MGM Fire Globally • $223 million in legal settlements • Extensive Changes in NFPA Including fire protection for seismic joints, elevator standards, smoke-proof enclosures, active/passive fire protection systems • Evolution of the following building codes for high-rise buildings 1994 UBC, section 905 1997 UBC, section 905 2003 IBC, section 909 Agenda Fire Life Safety Building Codes • • • • History of the Building Codes Smoke Control Requirements Fundamentals of Smoke Control Systems Section 909 of 2003 IBC Code Overview Building regulations date back to the beginning of recorded history. The Code of Hammurabi (2200B.C) included simple but effective building code provision. “If any architect built a house so negligently that it fell down and killed the owner’s son, then the architect’s son was put to death.” In 1630, the City of Boston mandated that “no man shall build his chimney with wood nor cover his roof with thatch”. The enforcement authority is derived from the 10th Amendment of the US Constitution which gives states the right to legislate for the protection of the public health, safety and welfare. Code Overview History Prior to the issuance of the IBC, there were three organizations of building officials who were responsible for developing and enforcing building codes in the United States: Building Officials and Code Administrators (BOCA) in the Northeast and Midwest International Conference of Building Officials (ICBO) in the West Southern Building Code Congress International (SBCCI) in the Southeast Code Overview Definition “A combination of architectural, electrical & mechanical system design approach that utilized air flow and/or pressure to contain or remove smoke during a fire event” Code Overview Requirements High Rise Exit Enclosures Atriums Covered Malls Underground Building Code Overview Fundamentals Types of Smoke Control: Active: An active smoke control system utilizes mechanical air handling equipment, i.e. supply fans, relief fans or smoke exhaust fans to contain or remove smoke in the zone of origin. Passive: A passive smoke control system utilizes construction barriers to maintain the smoke in the zone of origin. (Typical passive smoke control systems would be found in equipment rooms, motel rooms.)

The overall concept includes a combination of mechanical systems and passive containment for the building. The building’s fire alarm system will be used to control, monitor and activate the mechanical smoke control systems. 2. Guestroom Levels (Levels 3-32). a. Upon activation of a corridor smoke detector, the corridor air-handling units will shut down and elevator lobby doors will close. The smoke exhaust fans located on the roof will start. Dampers will be installed on a common shaft that will normally be used to supply outside air to the corridors and provide smoke exhaust functions during an event/alarm. All dampers will close throughout the floors served by the common shafts except the exhaust dampers will open on the fire floor. Exhaust will be sized based on Section 905 of the UBC to maintain a minimum negative pressure of 0.05 inches of water column relative to the adjacent units, elevator lobbies and stairwell vestibules on the floor of origin. b. Each guestroom, elevator lobby, maid closet, and similar type room will be treated as passive areas. Units with interconnecting doors will be treated as one common passive area. c. The bathroom exhaust vents are not considered a part of the smoke control system, and are not subject to pressure or leakage testing. Exhaust fans serving the toilet rooms will continue to operate and be provided with emergency power. 22-inch sub-ducts will be provided within the toilet exhaust shafts. d. A minimum of 2 guestrooms per floor (one on each side of the corridor, with selection Means & Methods Commissioning Phases Life Safety System Design Review Are the smoke control diagrams complete?
